ELAsTlo-FLUID TURBINE.

Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed August 151 1904. Serial No. 220,696.

Be it known that l, OLE O. STORLE, a citi zen of the United States, residing at Burlington, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Elastic-Fluid Turbines, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

This invention relates to that class of turbines in which a wheel or runner is rotated by the impact of an elastic fluid against vanes or abutments with which the wheel or runner is provided. Its main objects are to utilizeto the greatest possible degree the kinetic energy of the elastic fluid, to avoid or balance end thrust on the bearings of the rotary tion followingl member of the turbine, and generally to improve the construction and operation of engines of this class.

lt consists in certain novel features of construction and in the peculiar arrangement and combinations of parts, as hereinafter particularly described, and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in the several figures.

Figure 1 is a transverse section on the line 1 1, Fig. 2, of a steam-turbine embodying the invention. Fig. 2 is a vertical longitudinal section on the line 2 2, Figs. 1 and 3, the secthe oblique direction of the passages in t e nozzle-disks and runner as indicated on Fig. 3 and Fig. 3 is a section on the line 3 3, Fig. l.

The casing of the turbine is composed of sections a a, separated in a plane at right angles to the axis of the turbine and secured together by flanges and bolts, so as to form a steam-tight joint between them. They are formed or provided with bearings b b for the runner-shaft and with a suitable base c for the turbine to stand upon. f Within the casing, at each end thereof, are iitted circular nozzle-disks d d, having annular channels c c in their outer faces next to the inner walls of the casing and assages j' f extending obliquely inward om said channels to the inner faces of the disks. 'Packing-rings (not shown) may be provided in the casing or disks to insure steam-tight joints between them on each side of the several channels e.

The runner or rotative member of the turbine consists of two circular plates or parts g, '.fitted to turn between the nozzle-disks d and mounted with a central plate or partition 7L upon a shaft i, which is fitted to turn in the bearings b of the casing. The plates or parts g, with the intermediate plate or partition 7L, are bolted. or riveted together and are lFixed or prevented from turning on the shaft fi by any suitable means, such as a squared enlargement ofthe shaft fitting a corresponding hole in the runner. Each plate or part g of the runneris formed in its inner face next to the partition 7L with radial channels or passages j, communicating at 'their ends with openings or passages k, extending obliquely outward through the plate. These openings or passages 7c are arranged in circular series to register at their outer ends with the inner ends of the similarly-arranged passages f in the nozzle-disks d, and the ends of each runner-passage, comprising a channel or passage j and two oblique openings or passages 7c, are arranged to register with nozzle-passages j', which communicate with different channels c. The passages fin the nozzle-disks and the passages 7c in the runner are correspondingly inclined in the same direction on both sides of the central partition 7L, as shown in Fig. 3.

The casing is formed on each side of the runner with a steam or other elastic -iuid supply connection and passage l, which communicates with the inner channel e in the adjacent nozzle-plate. lt is also formed around the periphery of the runner with an annular passage fm, communicating at suit able intervals through ports a with the runner-chamber and also with an exhaust port or passage o in the base.

The ruimer plates or parts g are formed or provided around theirperipheries with radiallyarranged vanes Vor abutments p, against which the adjacent nozzle-passagesf are directed.

lf desired, a channel may be formed in the casing communicating with the spaces or passages between the vanes p around the entire periphery of the runner.

My improved turbine operates as follows: Steam or other elastic iluid being admitted on both sides of the runner through the passages Z enters and iills the inner channels e, from which it is delivered through the inner row of oblique nozzle-passages f into the inner row of runner-passages 7c, passing thence into the next outer channels e through the radial passages y' and the next outer rows of registering passages 7c and f, and so on in and out through the successive rows or series of IOC IIO

connected and registering passages and channels, expanding by stages until it issues from the last rows of nozzle-passages ff against the vanes or abutments p and finally escapes through the ports n and passage m to the exhaust port or passage o. The impact of the numerous jets of steam or other elastic fluid directed by the nozzle-passages f through the runner-passages 7c against the side walls of the radial passages y', which serve as vanes or abutments, and the reaction of the steam or other fluid as it escapes through the passages c and f in a reverse direction from the outer ends of the passages y' cooperate to impart a powerful forward impulse to the runner, and the gradually-increasing number and area of the connected and registering channels and passages as the steam or elastic fluid approaches the periphery of the runner permit of successive stages of expansion and the utilization of the kinetic energy of the steam or other motive liuid to the fullest extent.

It should be understood that the passages c in the runner are to be made close together or arranged so that some of them will always be in register or communication with nozzlepassages ff.

The nozzle channels or chambers e c need not extend, as shown, continuously around the disks d d, but may be of segmental or other form, although the annular form shown is considered preferable.

Essentially the same arrangement of parts and passages may be embodied in a turbine having one or more sets or series of nozzles and runner-passages on one or both sides of the runner or having a casing, one or more nozzle plates or bodies, and a runner of different shapes, but substantially the arrangement and the forms shown are preferable, as

' they are simple and easy to make and reliable and effective in operation. In short, various modifications in the details of construction and arrangement of parts may be made without departing from the principle and intended scope of the invention.

' I claiml. In an elastic fluid turbine the combination of a casing provided with nozzles arranged in a number of separate series and a runner having passages each adapted and arranged to receive the iuid from one series of nozzles and to discharge it back into another series in a direction to react upon the runner and cooperate with the directvimpact of the fluid entering said passages in driving the runner forward, substantially as described.
